Oakville is a crack that appears without any impact damage to the windshield. These cracks are the result of pressure or stress on the glass from internal factors such as temperature changes, uneven pressure, flaws in the glass, or manufacturing defects. They often start at the edges of the windshield and may spread quickly if not addressed right away.

One of the most common causes of these cracks is sudden variations in surface temperature. For example, if your windshield has been exposed to direct sunlight for an extended period of time and then you turn on the air conditioning or hose down the vehicle, it will cause the glass to expand rapidly which leads to cracks.

What Causes a Car Glass Stress Crack and How to Prevent It

Another factor that can lead to these cracks is vibrations from driving on rough roads or hitting potholes. These jolts can create tension in the entire frame of the vehicle which leads to stress cracks. Overtime, these cracks can also weaken the structural integrity of your windshield which poses a safety risk.

This is especially dangerous if the cracked area of your windshield is near the driver’s line of sight. For this reason, it is very important to have any cracks in your windshield checked by a professional immediately. To help prevent these stress cracks from occurring in the first place, we recommend parking your car in a shaded area and avoiding excessive temperature fluctuations in your vehicle. It is also a good idea to never use hot water to remove ice from your windshield as this can cause the cracks to accelerate.
